HAND BORING- MACHINE.

Application filed December This invention relates to improvements inhand boring machines and more particularly to that class of hand boringmachines covered by my previously issued United States Patcut, No.1,527,493, dated February 24th,

1925, and the objects of the present invention are to provide a handboring machine in which means are provided for rotating the auger at anypoint therearound instead of, as in the above-mentioned patent, from theextreme end.

\Vith these and other objects in View the invention consists essentiallyin the combination, with a boring auger and means for l5 suitablysupporting it, of an interiorly threaded sleeve for the auger providedwith a collar designed to engage with the hub of a gear wheel which, inturn, meshes with a hand operated pinion whereby the gear wheel isrotated, at any point thereof, to

operate the auger and a pivotally mounted pin for locking the gear Wheelto the auger in such manner so as to permit the latter to travel in thesleeve.

Referring now to the drawings in which like characters of referenceindicate corresponding parts in each figure,

Figure 1 is a side elevation of an embodiment of my improved auger setup,

Figure 2 is a plan view,

Figure 3 is a vertical section through the sleeve and collar, and

Figure 1 is a section on line Jr-A of Figure 3.

Referring more particularly to the drawings, Figure 1 illustrates themachine as a whole set up ready for operation on the face A of a vein ofsoft mineral such as coal or the like. The machine comprises the mainauger 10 which is provided, at an suitable point in its length, with asleeve 12 interiorly threaded at 13 to engage with the auger thread 1%.The sleeve 12 is formed with an enlarged collar 15 adapted to engagewith the lower hub por tion 16 of a gear wheel 17 provided with anextended upper hub portion 18. A suitably formed support 19 is formed onthe sleeve 12 and mounted therein in a bearing 20 is a spindle 21, onthe inner end of which is keyed a pinion 22 designed to mesh with thegear wheel 17, the outer end of the spindle 21 being provided with acrank and handled operating member 23 so that, on the latter beingturned, the gear wheel 17, through the pinion 22, is rotated and with it2, 1925.

the hub portion 16 within the collar 15 and i the extended hub portion18.

To cause the auger to rotate I provide the hub portion 18 with a lockingpin 24, screwthreaded at 25 and designed to loosely engage with theauger in such manner as to rotate it but atthe same time permit theauger, when rotated, to travel through the sleeve 12. This locking pin24 is carried in one end of the embracing member 26 supported by thebracket 27 on the hub portion 17, the other end of this member beingsuitably bent and extending through and into the hub, as at 28, toregister with the pin 24-, see Figures 2 and 4, one on each side of theauger member 10.

For supporting the auger in operative position, as illustrated in Figure1, the construction is similar to'that already described in mypreviously issued, above-mentioned United States application. It is notconsidered necessary, therefore, to go into the details further.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention, within thescope of the claims, constructed without departing from the spirit orscope thereof, it is intended that all matter contained in theaccompanying specification and drawings shall be interpreted in anillustrative and not in a limiting sense.

hat I claim as my invention is:

In a device of the character described and in combination, an auger, aninternally threaded sleeve adapted to engage with the auger thread andformed with an enlarged collar, a gear wheel formed with a tubular hubadapted to engage with said collar, a supporting arm on the sleeve, anda spindle in said arm, and a pinion on said spindlev adapted to meshwith the gear wheel, manually operable means connected to the spindle, asupporting bracket on the tubular hub, a suitably bent bracket membersupported therein, a screw-threaded locking pin adjustably mounted inone end of said bracketand adapted to extend into the hub to engage anddisengage with the anger, the opposite end of the pin-carrying bracketbe ing suitably bent to register in spaced relationship with said pin.

In witness whereof I have hereunto set my hand.

GEORGE WESTON SLATER.
